The fabric is light, elastic, soft and very thin. I've had enough of protection for temperatures of 10-30 degrees, but much colder temperatures is definitely not suitable. I wear it either on the wrist or at the top and sunscreen when it is warm, or neck at night while hiking. Sweat and moisture to dry very quickly.
The black-green pattern I really like, looks really chic. I'm still me another order, as a gift.
